4 Claims.

Insulating grips for cooking utensil handles often are made ofnon-conducting plastic material by molding. The grips may be one-piecemoldings, molded around the handle, or attached thereto by means ofrivets or the like. Grips for strap handles, and particularly for curvedstrap handles such as bails, usually are molded around the handle in asingle piece, but sometimes are made in two pieces and riveted to thebail handle.

Ineither case, replacement of the grip when it becomes loosened orbroken in use in either very dimcult for the'ordinary purchaser ofcooking utensils or entirely beyond his skill. Furthermore, in theriveted structures, the rivet heads are generally at or near the surfaceof the non-conducting grip, and the rivet shank is in direct contactwith the metal ball at the point at which it passes through the bail.The rivet heads heat up in such cases and may burn the hands of theuser. It is anobject of my invention to overcome these and otherdisadvantages in the construction of heat-insulating grips for handles.More particularly, it is an object of my invention to provide aninsulating grip that is simple in construction and efficient inoperation. Specifically, it is an object of my invention to provide aneasily replaceable two-piece insulating grip for strap handles, such asbails, which is affixed to the bail in such manner that the fasteningmeans are completely insulated from the metal of the bail to preventconduction of heat to the surface of the grip.

Referring now to the drawing in which like reference numerals indicatelike parts through the several views:

Fig. l is a view, partially in longitudinal section and partially inelevation, of a two-piece grip made of non-conducting plastic materialaccording to my invention and attached to the bail of a utensil;

Fig. 2 is a longitudinal sectional view of the top member of thetwo-piece grip;

Fig. 3 is a bottom plan view of the top member illustrated in Fig. 2;

Fig. 4 is a longitudinal sectional view of the Fig. 5 is a top plan viewof the bottom member illustrated in Fig. 4;

Fig. 6 is a transverse section taken on the line VI-VI of Fig. 1;

Fig. '7 is a transverse section'taken on the line VIIVII of Fig. 1;

Fig. 8 is a transverse section taken on the line VIII-VIII of Fig. 2;

Fig. 9 is a transverse section taken on the line IX-lX of Fig. 2;

Fig. 10 is a transverse section taken on the line X-X of Fig. 4; and

Fig. 11 is a transverse section taken on the line XIXI of Fig. 4.

The insulating grip of my invention is applicable to any type of cookingutensil handle and is particularly suitable as a grip for bail handles.The drawing accompanying this application shows a preferred form of myinvention in which the grip is attached to a suitably apertured bail. Itis to be understood that the invention is not limited to the exact formillustrated in the drawing accompanying the'application, the insulatinggrip. of the invention being susceptible to numerous adaptations whichwill be manifest to one skilled in the art to which the invention isdirected.

In the form shown, the bail or handle is substantially arcuatelengthwise and is also arcuate in transverse section over most of itslength, as indicated at 2|], and best shown in Fig. 7, but centrally ofthe grip location has a portion 2| substantially that in transversesection, as best shown in Fig. 6. An aperture 22 extends through thehandle centrally of the grip location, and an aperture 23 extendsthrough the handle adjacent each end of the grip location. Between eachaperture 23 and the central aperture 22, another aperture 24 isprovided.

The top member 25 of the grip has a central boss 26 having a shoulderand a reduced end portion and hollow bosses 21 adjacent its ends.Between the boss 26 and the bosses 21 are solid bosses 28. An internallyscrew-threaded insert 29, of brass or the like, is provided in eachhollow boss 21, the grip member'25 being molded around the inserts sothat the inserts are held positively in place.

The bottom grip member 30 is provided with'a central well 3|surroundedby a raised portion 32.

.The Well 3| is of a size and shape to receive the reduced end portionof the boss 26 on the top member. Thebottom member 30 adjacent each endhas a well 33 and a countersunk passage 34 extending through the member30 into the base of each well '33. The countersunk passage 34 is adaptedto register with the threaded insert in the hollow boss 21 of the topmember. Between the well 3| and the wells 33, short bosses 35 of thesame cross sectional size and shape as, and adapted to "register with,the aforementioned bosses 28 on the top member 25, are provided.

In assembling the grip, the reduced end portion of the boss 28 isinserted through the aperare properly located on the handle, the bosses28 and 35 meeting through the apertures 24, and the hollow bosses 21extending through the apertures 23 into the wells 33. It will be seenthat in this position, the portion of the bail surrounding the centralaperture 22 is gripped by the shoulder of the boss 26 and by the raisedsurface 32, and that each passage registers with the threaded insert 29in a hollow boss 21. A fiat headed screw 36 is inserted through eachpassage 34 into the screw-threaded insert 29 in the corresponding hollowboss 21. The assembly is completed by tightening the screws 36.

When the ball or handle is not in a constant or uniform arc, the gripmembers are made correspondingly eccentric. In some instances, thiseccentricity is too slight to be apparent immediately to the eye, but inthe event that one or both of the members were reversed, a poorlyfitting grip would result. In such cases, the grip members may be markednear one end, as by the front markers 31 and 38, which are provided inthe molding of the grip so that reversal of the members in assemblingthem may be avoided.

By this construction, the handle grip is readily and easily assembled,and comparatively easy to manufacture. The hollow bosses 21 surround theinserts 29 and the shanks of the screws 38, completely insulating themfrom the ball or handle so that the heads of the screwsdo not becomeheated.

If a grip becomes worn or broken in use, no special skill is required toremove it and secure another grip in place. It will be seen that the 1top and bottom members are so formed that they cannot be confused, andthat the top member is in the form of a shallow channel, while thebottom member is in the form of a deeper and wider channel receiving thetop member, to provide asmooth surface on the grip.
